SPECIFICATION forming part of Letters Patent No, 421,162, dated February 11, 1890.

Application led October 26, 1889. Serial No. 328,292. (No model.)

T0 @ZZ whom t may concern:

Be it known that I, Lnwrs S.CALDER, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in vaponburners; and it consists, substantially, in such features of arrangement, construction, and combinations of parts as will hereinafter be more particularly described, and pointed out in the claims.

The invention has for its object to provide a vapor-burner in which oil-vapor is first generated, then superheated and conducted to a point ot ignition, where it is burned with atmospheric air for the purposes of heating and cooking.

The invention has for its further object to provide a vapor-burner in which little or no condensation of the vapor takes place, and also to render the burner of economic construction, easy to manipulate, and readily repaired when out of order, substantially as will hereinafter more fully appear on reference to the accompanying drawings,wherein- Figure l represents a vertical sectional elevation of a vaponburner constructed in accordance with my invention; and Fig. 2 is a view in perspective of the several parts constituting my improved vaponburner, the said parts being separated from each other andv relatively arranged so as to enable their construction to be seen and understood. Fig. 3 is a top or plan view of the mixing-chamber, and Fig. 4l is a View ot such chamber to indi cate the arrangement and working of the rod which enters the same from the side.

In carrying my invention into effect I arrange a portion of the oil-supply pipe in such proximity to the side of the burner proper as that it becomes very highly heated after the vaporization has beenstarted, and as this port-ion of the supply-pipe is always in direct contact with the flames issuing from Jthe burner the same thereby becomes a genn erating=cha1nberI The said generator is iitted in the side of a superheating-chamber, into which the vapor passes and becomes superheated before passing to the jet or point of ignition.

I provide a mixing-chamber, preferably of conical form, having air-inlets and provided at its lower end with a hollow neck that is slightly contracted centrally, so as to form a guide for the passage of the pipe which leads downward from the bottom of the superheater, and also to leave an open chimney or inlet for the passage of air from beneath and at a point contiguous to the jet or iiame. Surrounding the su perheater and supported on top of the mixing-chamber is a perforated hood or spreader provided with legs to main tain the same slightly above the top of said inixing^chan1be13 so as to leave open Espaces all around for the air to be spread outwardly and burned in a manner hereinafter more fully understood. Entering the mixingchamber from one side is a rod or valve, by means of which the passage of air up through the mixing-ehamber is retarded sufficiently long to enable a most thorough and complete admiXture of the air and oil-Vapor, thereby insuring perfect combustion of every particle of gas.

Reference being had to the several parts of the drawings by the letters marked thereon, A represents the mixing-chamber, that is preferably conical in form and having a lower neck a, that is slightly contracted at l), so as to form a guide c for the passage of the pipe d, leading from the bottom of the superheater B, and also to leave an open iiue or chimney e, to admit air immediately over the j et-orice f. This mixing-chamber' is provided in its top with an opening g, that is approximately oval in shape, the same being in aline with both the guide c and the chimney e. Said opening is sufficiently large to leave a space all around the pipe d, so as to be entirely enveloped by the burning gas or vapor.

Extending upwardly from the top of the mixingchamber A is a bracket 7L, which receives the upper portion of the generating supplypipc D, and thus serves to support both the super-heater B and the said pipe in position, The mixing-chamber is further provided with a series of openings e', for admitting air to the interior thereof, and entering the said chamber from one side is a small rod j, which passes through a plane intersecting a vertical plane taken through the opening g, and by means of this rod the currents of air entering the mixing-chamber from the sides and bottom will be broken or retarded to such an extent as to cause a thorough admi'xture of the air and gas.

C represents a hood or spreader that is formed with the legs m, which are recessed at fa, so as to fit upon the upper edge of the mixing-chamber and be thereby supported above the said mixing-chamber in the manner shown in Fig. 1. This construction leaves open spaces 0, out through which the combined air and gas will be spread in such manner as to cover a very large surface and create an intense heat. Flames will also issue through the perforations s insaid hood, and it Will be apparent what superior results c an be attained through the medium of such simple apparatus and small amount of fuel. The mixing-chamber is also notched or cut out at u, so as to fit around the supply-pipe snugly into place.

In the drawings I have shown the side of the mixing-chamber as provided With a pro- Jection t, this being to enable the burner to be attached to a support-such,for instance, as in Fig. l. In this figure I have shown the burner as arranged beneath the top or table E of an ordinary vapor-stove, this being one of the uses for Which my invention is intended.

From the foregoing description it Wi'll be seen that a clean, neat, and simple form of burner is had, and it is obvious that immaterial changes could be resorted to in the general construction' and arrangement of parts Without departing from the invention; hence I do not Wish to be understood as limiting myself to the precise details of construction and arrangement shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a vapor-burner, the combination, with the conical mixing-chamber having the airflue and guide and provided with air-inlets, of the superheater having a depending tube entering the guideand the perforated hood or spreader having the supporting-legs, said mixing-chamber being provided in its top With the oval-shaped opening, substantially as described.

2. In a vapor-burner, the conical mixingchamber having a series of air-inlets and formed with the guide and air-Hue, the same having also in its top a double or approximately-oval shaped opening, substantially as described.

3. In avapor-burner, the combination, with the conical mixing-chamber having the air- Hue and guide and provided With air-inlets, of the superheater having a depending tube entering the guide, the perforated hood or spreader having the supporting-legs, and the rod entering the mixing-chamber, substantially as and for the purpose described.

In testimony Whereoi` I affix my signature in presence of three Witnesses.
